Quote:According with Standardized Galactic Law, every spaceship entering the atmosphere of a planet with a pre-hyperspace civilization (like Earth) must have a Blurrer installed.

This device emits sub-quantum metawaves that render any optical or electronic imaging devices useless, by making their lens go out of focus.

Or at least something very close to that. If they were close to earth and checking us out, they must be technologically superior to us. Why would they let us detect their presence? I would certainly want to be very stealthy if I were checking out their lair!

Hail Satan!

Quote:I have done enough reading on Sagan and on this theory. I looked at both of the opposing sides. I have made my conclusion based off research of some fine data.

Interesting. Might I ask for more detail on your data and your conclusion? (You've got me genuinely curious here; I promise I'm not just trying to draw you out so I can deliver a Scientific Smackdown.)

On matters astronomical, I like to think I'm pretty well-read for a non-professional, but I've never gotten deeply into things like archaeology. And so if I'm missing any pieces of this puzzle, I'd like to know.

Quote: But as Asmedious said- if it is true, it has no effect on our lives. When it does effect…. Well, I just hope it won't be in a negative way..

Let me explain myself:"If it is true"= if there are currently aliens out there"It has no effect on our lives"= in the present, as long as they don't interfere- they are not relevant to my day to day life… (by "our" I meant Satanists… since we are not worshiping aliens as gods)"When it does effect"= if they reveal themselves to the whole world and there will be proves of their existence and we will come in contact with them. "I just hope it won't be in a negative way"= I hope they don't blow us up or anything.

If you meant the time it takes for a "day" to manifest on the moon... well... it doesn't. It has a "dark side" for a reason

Not true. The moon has a side that never faces earth, but that side is not any darker than the near side (if anything it's actually brighter); it regularly faces the sun, whenever the moon is on the sunny side of earth.

However, the moon's rotational period does precisely match its orbital period, and therefore a lunar "day" is the same as the lunar month.

Incidentally, slightly off on the orbital period as well, at least by my reckoning.

The sidereal period of the moon is is 27 d 12 h 44 min; the sidereal period is the time it takes a celestial body to complete one full revolution.

The synodic period is the time it takes said object to reappear at the same point in the sky, relative to the sun, as viewed from earth. The synodic period for the moon is the number you gave.

Perhaps it is stickling for details, but my logic says the sidereal period is the "true" orbital period here, since the synodic period is strictly relative to earth observation.

All of which leads me to conclude that most likely Magister Nemo did not mean to suggest that the human circadian rhythm when removed from natural day/night cycles is relative to the periods of the moon (har, har, har ).

I knew this is what you meant all along...I just want to know why you feel this way. You can't make a statement like that without explaining it. Even if humans just observed either primitive or intelligent alien life without interference, nothing will ever be the same again. It's interesting to know exactly how you will be exempt.

Quote:(by "our" I meant Satanists… since we are not worshiping aliens as gods)

I know. I don't expect that kind of answer here from anyone. However, I still wouldn't be too quick to answer for everyone either. Alot of people go against everything they believe in when their lives are threatened. If aliens were strong enough to enslave humanity, would you be enslaved to save your life or would you rather let them kill you?

There's actually an equation for finding out how many technologically advanced civilizations are out there. I'll sum it up from my text book. (Horizons: 6th Edition by Micheal A. Seeds.)

Nc = (N*)(fp)(nLZ)(fL)(fI)(Fs)

Nc is the number of communicative civilizations.N* is the average number of stars in a galaxy.fp is the probability that a star has planets.nLZ is the average number of planets suitably placed in the "life zone"fL is the probability that life will originate if conditions are suitable.fI is the probability that intelligent life will develop.Fs is the fraction of a star's life during which a civilization is communicative.

A little side note on what a "life zone" is. A life zone is a region around a star in which it is not too hot or too cold for life to develop and survive. Now my favorite part, number crunching. I'll use the most pessimistic values for all of the above variables.

N* = (2)(10^11)fP = 0.01nLZ = 0.01fL = 0.01fI = 0.01Fs = 10^-8

Plugging these in gives a value of (2)(10^-5) communicative civilizations per galaxy, or 1 per 50,000 galaxies.

This doesn't seem like a lot. However, the one thing that most people fail to grasp is the shear size of the universe. There are an estimated 100 BILLION galaxies. That would mean that there are 2,000,000 communicative civilizations in existance right now, and that's the minimum value. Of course, if there's only 1 civ per 50,000 galaxies, then the odds are that we will never make contact with one or even know that they exist. So, is there intelligent life elsewhere? Statistically speaking, it's very, very likely. Will we ever communicate with them or be visited by them? Hard to tell, but probably not.

Going by these statistics, the possibility of communicating with aliens does seem very hopeless if Earth is the only planet in The Milky Way or other nearby galaxies that sustains life. Unless there is intelligent life somewhere close by in our galaxy. I think chances are very good.
